Astronomy is the study of planets, stars,
and galaxies. It is seperated into two important categories such as astrometry and astrophysics. Astrometry
is a branch of Astronomy that deals with the locations, distances and movements of stars, and other astronomical objects.
Astrophysics is a branch of astronomy that focuses on the physics of the universe, such as physical properties. These properties
contain luminsity, density, temperature, and chemical composition of celestial objects.
